Final answer:
The fattier milk formed after the foremilk in breastfeeding is called hindmilk. It is creamy in appearance, high in fat, and provides essential nutrients to satisfy an infant's hunger.
Step-by-step explanation:
The milk that follows the foremilk during breastfeeding is known as hindmilk. This is the fattier milk that is produced toward the end of a feeding, which appears opaque and creamy. Unlike foremilk, which is watery and rich in lactose and protein to quench the infant's thirst, hindmilk is rich in fat and serves to satisfy the infant's appetite, providing essential nutrients for growth and development.
During lactation, suckling triggers the release of oxytocin, stimulating myoepithelial cells to contract and release milk from the alveoli. Hindmilk represents the latter phase of nursing when the more concentrated, nutrient-dense milk is delivered to meet the energy needs of the growing infant. Breast milk, including both foremilk and hindmilk, undergoes changes in composition to match the baby's needs during each stage of feeding.
